Abstract

We tried to find how much Crown tip, modified from conventional phaco tip in angle and shape, shortens the phacoemulsification time, how much it improves the recovery of vision after cataract surgery, and how it affects the incidence of complications. We classified patients into 6 grades according to LOCS III. The cataract surgery performed with Crown, 0 degree C and 45 degrees C tip in the same condition. We retrospectively examined the patients who could be followed for 2 months after cataract surgery. Most patients were grade 4 and 5. The results showed that phacoemulsification time was 43.20+/-12.59 and 58.30+/-11.91 sec.in grade 4 and 5 with Crown tip. Compared with others, it was statistically significant with probability of 0.0389(P<0.05). There was no difference in intraoperative complication and postoperative best corrected visual acuity. Conclusively, we decided that Crown tip could reduce the phacoemulsification time in moderate cataractous lens but further investigation is needed.
